Product details
Overview
MC74VHC1GT08MU3TCG from onsemi is a single 2-input TTL-level AND gate in a 1.0 mm × 1.0 mm UDFN6 package, operating from 2.0 V to 5.5 V, with 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and input/output over-voltage tolerance up to 5.5 V. It enables level-shifting between 3 V and 5 V logic domains in compact portable electronics.
For engineers reviewing the MC74VHC1GT08MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 5.5 V), IOFF partial power-down support, 5.5 V tolerant I/O independent of VCC, and UDFN6 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard positive-logic AND functionality with Schmitt-trigger–free CMOS circuitry optimized for low static current and fast switching. Its TTL-level inputs accept VIH ≥ 2.0 V (at VCC = 5.5 V) and VIL ≤ 0.8 V, distinguishing it from the CMOS-threshold MC74VHC1G08 variant.
The UDFN6 package features a 0.35 mm pitch, exposed pad (non-electrical), and pin 1 marked by rotation (270° clockwise). Input and output structures tolerate 5.5 V regardless of VCC, enabling safe interfacing between mixed-voltage subsystems without external clamping diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V systems without level translators |
| tPD (Typ) | 3.5 ns at VCC = 5.5 V, CL = 15 pF - enables timing-critical signal gating in high-speed digital control paths |
| IOH/IOL | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small LED indicators directly |
| VIH/VIL | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.5 V - ensures reliable recognition of legacy TTL outputs |
| I/O Voltage Tolerance | Up to 5.5 V independent of VCC - eliminates risk of damage during hot insertion or supply sequencing mismatches |
| IOFF Support | Active when VCC = 0 V - prevents back-driving and current leakage in partial-power-down modes |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
Pinout & Package
The MC74VHC1GT08MU3TCG uses a 6-pin UDFN package (Case 517BX), 1.0 mm × 1.0 mm, 0.35 mm pitch, with pin 1 identified by 270° clockwise rotation. The exposed pad is non-functional and not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B (Input) | Second logic input; accepts TTL- or CMOS-level signals up to 5.5 V |
| 2 | A (Input) | Primary logic input; same voltage tolerance and threshold as Pin 1 |
| 3 | GND | Ground reference for all internal circuitry and I/O structures |
| 4 | Y (Output) | AND result (A • B); drives loads up to ±8 mA while maintaining rail-to-rail swing |
| 5 | NC | No internal connection; must be left floating or tied to GND per layout best practice |
| 6 | VCC | Positive supply; powers internal logic and defines output voltage levels |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Ensures interoperability with legacy 74LS/74ALS outputs without pull-up resistors or translators |
| 5.5 V over-voltage tolerant I/O | Allows safe connection to 5 V buses while powered from 3.3 V or 2.5 V rails - no external protection required |
| IOFF partial power-down mode | Blocks current flow through inputs/outputs when VCC = 0 V, preventing back-powering of inactive subsystems |
| Ultra-small UDFN6 footprint | 1.0 mm × 1.0 mm area saves >60% board space vs. SOT-23-5, critical for wearables and sensor nodes |
| AEC-Q100 qualified option | MC74VHC1GT08MU3TCG−Q variant available for automotive applications requiring PPAP documentation |

IC Role / Device Role / Timing Role: Low-power combinatorial logic element synchronizing asynchronous sensor status signals. Use Value: 2.0 V minimum VCC enables operation from coin-cell–derived rails; 1.0 mm² footprint fits tight space constraints near sensor array. |
Use Scenario: Door lock actuator enables only when both ignition status and door latch position signals are valid. IC Role / Device Role / Timing Role: Safety-critical hardware interlock gate in ASIL-B–relevant subsystem. Use Value: AEC-Q100–qualified variants ensure reliability; −55 °C to +125 °C rating supports under-dash mounting without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | CMOS input thresholds (VIH = 70% VCC), slightly higher ICC (max 10 µA vs. 40 µA), same UDFN6 package | Requires stable VCC for predictable VIH; less tolerant of slow-rising TTL edges | Select when interfacing exclusively with LVC-family outputs and minimal quiescent current is prioritized |
| 74AUP1G08GW,125 | Lower VCC range (0.8–3.6 V), 2.4 ns tPD at 3.3 V, smaller 0.8 mm × 0.8 mm XSON6 package | Not 5.5 V tolerant; unsuitable for 5 V interface or mixed-voltage domains | Select for ultra-low-power, single-rail 1.8 V/3.3 V systems where board area is more constrained than voltage flexibility |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1GT08MU3TCG uniquely combines TTL-level input compatibility, 5.5 V I/O tolerance, and industrial temperature range in a 1.0 mm² footprint - making it the only choice for robust 3 V/5 V bridging in space-limited, mixed-supply designs.

FAQ
What is the input threshold behavior of MC74VHC1GT08MU3TCG compared to MC74VHC1G08?
The MC74VHC1GT08MU3TCG uses TTL-level input thresholds: VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 5.5 V. In contrast, the MC74VHC1G08 uses CMOS-level thresholds (VIH ≥ 3.85 V, VIL ≤ 1.65 V at VCC = 5.5 V). This makes MC74VHC1GT08MU3TCG compatible with legacy 74LS outputs without pull-ups, while MC74VHC1G08MU3TCG requires clean CMOS-level signaling. Both share identical output drive, packaging, and voltage tolerance.
Does MC74VHC1GT08MU3TCG support partial power-down (IOFF)?
Yes, MC74VHC1GT08MU3TCG supports IOFF: when VCC = 0 V, both inputs and output enter high-impedance state with leakage ≤ 10 µA, preventing back-current flow into powered subsystems. This feature is confirmed in the DC Electrical Characteristics table (IOFF parameter) and applies across the full −55 °C to +125 °C temperature range - critical for battery-backed or hot-pluggable systems.
What is the exact pin 1 marking and orientation for MC74VHC1GT08MU3TCG in UDFN6 package?
Per the datasheet ordering information, MC74VHC1GT08MU3TCG uses Case 517BX (1.0 mm × 1.0 mm, 0.35 mm pitch) with pin 1 orientation marked as "K" and rotated 270° clockwise. The top-side marking consists of a 2-character device code followed by date code; pin 1 is located at the corner diagonally opposite the marking's bottom-right character, verified by the mechanical drawing in Figure 2 (UDFN6 pin assignment).
Can MC74VHC1GT08MU3TCG safely interface a 5 V microcontroller GPIO to a 3.3 V FPGA input?
Yes - MC74VHC1GT08MU3TCG can safely perform this level shift. Its inputs tolerate up to 5.5 V regardless of VCC, so a 5 V GPIO drives Pin 1 or 2 without damage. With VCC = 3.3 V, the output (Pin 4) swings rail-to-rail (0 V to 3.3 V), matching the FPGA's input requirements. No external resistors or translators are needed, and the 3.5 ns propagation delay preserves timing integrity.
Is MC74VHC1GT08MU3TCG qualified for automotive use?
The base MC74VHC1GT08MU3TCG is not automotive-qualified, but the −Q suffix variant (MC74VHC1GT08MU3TCG−Q) is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C) and PPAP-capable. This variant undergoes additional stress testing and traceable lot control - required for body electronics, lighting, and infotainment modules. Standard parts lack the automotive-specific qualification documentation and screening.
